EV Charger Installation: Complete Guide for Hampshire Homeowners

By CRG Direct Electrical Team 18 January 2025

The transition to electric vehicles is accelerating across Hampshire. With government incentives, expanding charging infrastructure, and decreasing battery costs, more homeowners are making the switch to electric mobility. Installing a home EV charger provides convenience, cost savings, and the foundation for a complete renewable energy ecosystem.

Why Install a Home EV Charger?

Convenience and Flexibility

Home charging eliminates the need to find public charging stations and provides complete control over your charging schedule. Most EV owners complete 80% of their charging at home, making a dedicated home charger essential for optimal EV ownership experience.

Cost Savings

Home electricity rates are significantly lower than public charging costs. Typical savings include:

  • Home charging: 7-15p per kWh
  • Public rapid charging: 35-50p per kWh
  • Annual savings: £400-£800 for average users
  • Property Value Enhancement

    Properties with EV charging capability command premium prices and appeal to environmentally conscious buyers. Estate agents report that EV charging infrastructure increases property desirability and market value.
